C1 Rub Sister-in-law's Back

"Mm …" "Hm …"

In the room, the high-pitched moans of a woman could be heard. I know, it must be my sister-in-law who can't stand the loneliness anymore!

"What are you looking at? "Little bastard, you're just a burden. Why didn't the one who died be you?!"

My name is Cao Li, I'm a high school student. Because people are more solitary and unsociable, the students at school normally don't pay much attention to me. However, it's good to have some peace and quiet. Right now, the one who is cursing me is my sister-in-law.

The only person that was good to me last year, my big brother, suddenly died in a car accident, and after my big brother left his will, my sister-in-law had to raise me until I became an adult, otherwise she would have to go out clean.

Heh, even though she agreed to raise me to adulthood, it doesn't stop her from making things difficult and insulting me.

Even though she would always hit me or scold me, it was enough for her to stop. But now, even if I cared about her, I would still be insulted. I wanted to take revenge on her.

However, I didn't expect that the opportunity for revenge would come so suddenly …

That day, before she left the house, she ordered me to clean her up, but I found her secret in her room …

I picked up a photo. "Sister-in-law?" Her expression was hazy, her red lips were sexy and seductive, and the exposed clothes exposed her breasts, captivating others. However, there was a strange man at her side holding something as he greeted her.

I can't believe that my sister-in-law would be such a woman!

At first I was afraid, for I had stumbled on the secret my sister-in-law had kept hidden.

I searched online for information and finally understood that my sister-in-law's behavior was a kind of masochistic love, a kind of sexual eccentricity, also known as SM.

After understanding all of this, I started to think about how I should take revenge on her.

That night, I registered my account and added her WeChat, pretending to be a member of the masochist circles. It took her a long time to pass the test.

Very quickly, I sent her a message and she quickly replied.

Slowly, in the midst of our conversation, I discovered that my sister-in-law was full of servility. She was no longer as cold and arrogant as she used to be. This made me somewhat speechless.

As the conversation deepened, we became more and more familiar with each other, and then she told me that she wanted to receive my tutelage.

Of course I do, that's what I think! But I pretended to think for a long time before agreeing.

I gave her my first order: "You bathe in a bathroom with the person you hate the most at the moment."

Sister-in-law hesitantly refused, but under my mockery and ridicule, she still agreed.

I had just hidden my phone when heavy knocks sounded on the door. Following that, my sister-in-law called me to come out of her room.

"Little bastard, when you get to the bathroom, just rub my back!"

I awkwardly said, "This …" This isn't appropriate, is it? Sister-in-law, we are sister-in-law, men and women shouldn't be intimate with each other! "

Just as I said that, she raised her hand to hit me. I dodged quickly and dodged a slap.

She fiercely scolded him, "Why are your thoughts so dirty and dirty, and why are you helping me just to rub my back? What are you thinking about? Is this how teacher teaches you? I wonder if my eldest sister-in-law is my mother? " In the end, she told me that she was my sister-in-law and that she had to be respectful.

What a slut, she actually secretly gave me a new concept, telling me to rub her back!

After entering the bathroom, my sister-in-law took off her clothes, with her back to me, revealing her smooth jade back, long and straight jade legs, and her sexy and voluptuous butt. For the first time, I realized how beautiful my sister-in-law was.

Sister-in-law was actually quite a beautiful woman. Her skin was like snow, and her eyes were like a puddle of clear water. As she looked around, she had a refined and elegant demeanor that caused others to feel intimidated, feel ashamed of their inferiority, and not dare to blaspheme. As the receptionist of a large company, her appearance was the face of the company, and her figure was exceptionally good. With her figure, Arrowhead's beautiful figure, and her skin as white as jade, she exuded a fragrance that could only be found in teenagers. Previously, when they wore an OL suit, their chests had almost burst from the pressure.

Now, when she took off her clothes, I saw her smooth and delicate body again, and I felt sorry for her.

I stared at her curvy buttocks. Her skin was amazing to the extreme. I couldn't help but feel that it wasn't too much use to her.

The gully between the two perfectly round and fragrant buttocks was even more enchanting to me, as if there was a devil calling me from within.

At that moment, I even had the urge to sink into the gap between my two fragrant buttocks and let my sister-in-law pinch me.

"What are you standing there in a daze for, hurry up and get over here and rub my back, you heartless thing!"

After sister-in-law's curses, I came back to my senses. I placed my hands on her smooth and beautiful back and she couldn't help but moan … Listening to the ecstasy of the sound, I couldn't help but feel a tightening beneath me.

But at that moment, for some reason, she suddenly slipped and quickly retreated.

She backed away quickly, but I couldn't react.

Thus, the towering figure beneath me accidentally charged into the gap between her two fragrant buttocks …
